Base of aquifer contours for the Northern High Plains aquifer

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: February 10, 2026 | Last Modified: 2020-11-17T00:00:00Z
Several pre-existing datasets that characterize portions of the Northern High Plains aquifer base were merged together in order to define the entire base of the Northern High Plains aquifer. This digital dataset consists of the aquifer base elevation contours (100-foot contour interval) for the northern portion of the High Plains aquifer in the central United States. The boundaries were chosen to simplify boundary conditions for a computer simulation model being used for a hydrologic study of the Northern High Plains.
